To all whom t may concern.-

Be it known that I, ROBERT J EWELL, a citizen of England, residing at 9Victoria Road,

. specification.

My invention relates to apparatus for con- -trolling the quantities ofliquid-such as spirits, wine, tim-drawn oft through cocks and to effectthe registration either of such quantities or of their money value, inorder to prevent fraud on the part of the servants who draw off theliquid and dispense it to the customers. Such apparatus to be ofpractical value must be so arranged that it will effect the registrationof the discharge not only of a maximum quantity of liquid, but also ofany desired different fractions of that quantity. For this purpose Iconstruct the apparatus as I will describe, with reference to theaccompanying drawings, in which- Figure 1 shows a front View of theapparatus; Fig. 2, a back View; Fig. 3, a cross-section; Fig. 4, a partview of plate D; Eig. 5, a detached View of contact-disk S2, and Fig. 6a front view of two sets of apparatus contained in a casing.

A is a cylinder of definite capacity equal to the maximum quantity ofliquid which is required to be drawn off at one time. In this cylinderare a number of taps B B2 B2, tbc., passing through it at differentlevels, each tap being thus enabled to draw off a diiierent quantity ofliquid-that is to say, assuming the cylinder to be full and the top tapB to be opened, this will discharge, say, two pennyworth of liquor. Thenif this tap be closed and, after illing A again, B2 be opened this willdischarge three pennyworth,

and so on, while if the bottoni tap B3 be opened the whole contents ofthe cylinder will be discharged. These taps have an opening at b'for theentrance of the liquor, and another opening b', which when the tap isturn ed half-ro und fro m the closedin to the open position is broughtopposite the opening of a branch c c2, &c.,on a pipe O, the lower end ofwhich is connected to a discharge-nozzle O. The relative positions ofthe openings b and b are by preference so arranged that when b is in theopen or discharging position b is at the uppermost part of the tap, sothat the liquid will be discharged exactly to that level.

The lower end of the cylinder A communicates by a branch pipe A with thepipe leading to the main cask or tank situated at a higher level, fromwhich the liquid is to be drawn, and on the branch A is a chamber A2,containing a shut-off valve A3, which is kept closed by a spring, so asto close the communication between the cask and the cylinder when thelatter is full and When liquid is being drawn off, the valve beingforced open against the spring, as will be presently described, when itis required to iill the cylinder again after withdrawing a certainquantity therefrom.

Bearing upon the end of the valve-spindle a is a vertically-slidingplate D, working between guides D', fixed to the cylinder. This platehas openings th rough which pass th e projecting ends of the tap-plugs BB2, v&c. On these plugs are iingers E E2 tbc., which in turning the tapfrom the closed to the open position pass the noses of spring-catches EF2, tbc., pivoted on plate D, without actuating the latter; but when thetap is turned in the opposite direction for closing after the quantityof liquid has been lwithdrawn the finger E presses upon the top of thecatch I1" and in thereby forcing plate D downward causes this to openthe admission-valve A3 and allow the cylinder to be filled with liquidagain. The plate D has an arm D2 near its lower end, a pin on whichtakes into a notch in a disk G, so that when the plate is forceddownward, as described, it turns the disk somewhat., so as to bring abeak G therein behind a stop I on the armature-lever I of anelectro-magnet J, the armature being held by a spring K so that it willretain the disk G in the posit-ion shown and thus prevent the plate Dfrom rising and the valve A3 from closing. Vithin the cylinder A is aiioat L,`;

IOO

carried by a support which may lbe composed of a pin Figs. l and 2,located near the upper end of the cylinder, and which in rising, whenthe cylinder A has become filled, presses against a plate M, the steinof which passes through a guide on the top of the cylinder and carriesan linsulating-head M', on which rests a contact-piece N, to which isconnected the one lead of an electrical circuit O, in which is includedthe electro-inagnet J. The lloat, in pressing the plate M u pward,consequently causes N to make contact with a piece N', which is pivotedto a screw l), to which the other lead of the circuit 0 is connected.The circuit being thus closed, the electroanagnet is made to attract itsarmature l, and this is thereby made to release the beak of disk G, andthe plate .D being now free to rise it is pushed up by the spring of thevalve A, so that this now closes and cuts off the further supply. Inorder to break the circuit of the electro-magnetagain, as soon as thisaction is completed the plate D carries an arm d at its upper cud, whichon the rising of the plate presses upward against a tail N2 on the pieceN', and in thus forcing the latter away 'from N breaks the circuit.

It is essential with the above-described arrangement, tirst, that itshould not be possible to open one of the taps while the supply-valve Aiis open, and, secondly, that it should not bepossible after opening twotaps at the same time to close one tap and thereby effect the openingofthe yalre Aiiin the manner described, while the other tap remains open,as in either of these cases an unlimited quantity of liquid might bedrawn without being measured and registered. 'lhis is prevented by thefollowing arrangement: On the inner face ot' the plate D are fixed anumber of locking-pieces Q Q, tbc., with arc-shaped faces, as shown atFig. -1-, and on the tapplugs B D?, &c., are fixed arc-shaped cams RR,ttc. When the plate D is in the raised position and the taps are closed,the cams are in the position shown at R in Fig. 4, and in turning thelap into the open position the cam can just pass with its curved surfacebeneath the curved surface of the locking-piece, as shown as R2; butwhen the plate D is down and the supply-valve is open, the lockingpieccbeing dotted in the position shown at Q3, the cam R will, in attemptingto turn open the tap, butt against the edge of Q, and consequently itsmotion will be arrested before it can be brought into the open position.Again, assuming the plate l) to be in the raised position and that twoof the taps have been turned into the open position, then in turning oneot' these into the closed position the depression of the plate D cannotbe effected bythe pressure of the Yfinger L of the tap on the catch F,as above described, because the cam R of the other open tap, beingsituated un der the curved face ot its locking-piece Q, Prevents anydownward motion of D.

Both taps must therefore be turned so as to close the discharge-openingsand bring the cams from under thelocking-plates before the depression ofplate D and openingof the supply-valve can be effected.

For effecting the registrations on the counter according to the quantityof liquor drawn at one time, each tap-plug l D?, ttc., carries on itsrear end a disk S S2, the., ot insulating material, on the periphery ofwhich are contacts s s, which are in conducting-connection with theplugs l B2, uc., and through these with the cylinder A, to which, at anyconvenient point, the one lead of the electric circuit 'l of theregisteriiig-counter is connected, while the other lead is connected toa plate U, secured in an insulated mannerto the cylinder A and carryinga number of contactsprings u u? a, &e., which slide in contact with thedisks s S2, and consequently etl'ect a closing of the circuit', so as toactuate the counter every time one ot' the contacts passes underneaththe spring on the turning of the tap. The contact-ifiieces s s may bearranged in either ot' two ways: either there are half as manycontact-pieces as there are registrations to be effected on the counter,so that one-half of the registrations are effected on turning the tapopen and the other half on turning it into the closed positionthus inthe above-described arrangement the disk S of tap l would have only onecontactpiece, as on turning' open the tap this would register one pennyand on turning the tap back it would register the second penny-or thecontacts may be arranged to register only in one direction, in whichcase there would be as many contacts as there are units to register.With this arrangement the disk is made loose on the sleeve by which itis connected to the plug, and the slecvcs`-, which is of conductingmetal and is fixed to the plug, is Vformed with a stud s3, which litswith a small amount of play in a notch in the disk S2, as shown at Fig.5, and the one side of this notch is formed of insulating material,while the other side is of conducting metal, in connection with thecontacts ss. Thus on turning the plug into the open position the stud.sa presses against the conducting-piece oi' the disk S2, andconsequently the contacts s in passing under the springu2 effect theclosing of the circuit, as described, while on turning the plug inthecontrary direction Vfor closing the stud s will press against theinsulating material of the disk, and conscquently the contacts will notct't'ect the closing of the circuit. 'this arrangement rcquires to beused in those cases where the number of contacts to be made isuneven-was, for example, with the third tap.

Although the above-described construction of measuring and registeringapparatus is specially designed `for cases where it is desired to drawvariable quantities of.liquid, yet it will be evident that it may beequally well applied for always drawing one and the IOO IXO

same quantity of liquid by means of a single tap-such, for instance, asfor bottling purposes.

Having thus described the nature of this invention and the best means Iknow for carrying the same into practical effect, I claiml. In apparatusfor drawing off different denite quantities of liquid through cocks, avessel having two or more cocks at different levels for dischargingdiiterent quantities of liquid from it, a conduit connecting said vesselwith a supply-tank and provided with a shutoff valve automaticallyclosed -by a spring, asliding plate connecting the several cocks withthe sl'lut-off valve, whereby when the cocks are turned into the closedposition they eitect the opening of the sh ut-oi valve, andlocking-plates upon the said sliding plate operating in conjunction withcams on the cock-plugs, which prevent a cock from being opened while theshut-off valve is opened, and which also prevent the closing of a cock,so as to open the shut-off cock while a second cock remains open,substantially as described.

2. In apparatus for controlling and registering quantities of liquidsdrawn through cocks, a vessel having two or more cocks atdifferentlevels for discharging different quantities of liquid from it,a conduit connecting said vessel with a supply-tank and provided with ashut-off valve, a sliding plate connecting the several cocks with theshut-off valve, whereby when the former are closed they effeet theopening of the latter, while when cocks are opened the shut-oft valve iskept closed by locking-pieces Q Q2 upon the said sliding plate operatingin conjunction with cams R R2 upon cock-plugs BB2, which prevent a cockfrom being opened while the shutoff valve is opened, and which alsoprevent the closing of a cock, so as to open the shut-off valve while asecond cock remains open, and a contact device connected to eachcock-plug included in an electrical circuit actuating a registeringmechanism or counter, whereby on opening or closing the cock contactsare made in the said circuit, so as to register the quantity ot' liquiddrawn, substantially as described.

3.
